How Often Should You Check Your MERV 8 Filter for Wear and Tear?

As an expert in air filtration systems, I recommend replacing MERV 8 filters every 90 days. This is due to the type of oven installed in your home and how often it is used. If you notice a lot of dust in the air or on furniture after cleaning a room, it may be time to replace the HVAC filter. Additionally, if the boiler is running for longer than usual, it is likely time to change the air conditioning filter.

To determine if it is time to replace the filter, take a look at its current state. If it is covered in dust or shows signs of visible damage, it is time to replace it. For basic air filters from 1 to 3, brands usually recommend that you change them every 30 to 90 days. If someone in your family has mild to moderate allergies, you can use a better air filter or change it more often.

Thicker oven filters tend to last longer and provide more filtration over time, so they usually cost more than 1 or 2 oven filters. In larger homes where horizontal HVAC units are installed, the furnace filter is usually located in the garage, basement, or attic. Checking and replacing filters is something that anyone can do and it is not hard to tell when they are dirty. However, if your home air is dirty enough to require a higher MERV rating or if you need to change air filters more than once a month, it is best to have a whole-house air filtration system. Before you think about changing your home air filter or the type of filter you need, familiarize yourself with the location of the filters and check them regularly. As an expert in air filtration systems, I highly recommend replacing HVAC furnace filters regularly as an integral part of preserving the functionality of your system and keeping the air conditioning system free of contaminants.

It also helps to clean the indoor air you breathe. Ultimately, if you want to achieve 95% filtering efficiency with NIOSH-approved N95 respirators, they must be used properly. To ensure that your home's air quality remains healthy and safe for your family, I suggest checking your MERV 8 filter every three months for signs of wear and tear. If you notice any dust buildup or visible damage on the filter, replace it immediately. Additionally, if someone in your family has allergies or asthma, consider using a higher-rated filter or changing it more frequently.
